As shown in fig. 1, 5, and 6 (where a dotted line in fig. 6 represents warm light and a solid line represents cool light), the panel lamp chassis 1 of the present application is used to mount a light source module 2 and a cover 3. Chassis 1 includes two pairs of lateral walls 11 and two installation departments 13, two installation departments 13 set up side by side and install the light source module 2 that the panel light corresponds, two pairs of lateral walls 11 extend the formation to 3 direction slopes of face guard from each 13 both sides of installation department, two pairs of lateral walls 11 are arranged in between 13 outsides of installation department and installation department 13, the lateral wall 11 that is located the outside links to each other with face guard 3, the lateral wall 11 that is located the inboard links to each other, and leave the clearance with face guard 3, two pairs of lateral walls 11 configure into first plane of reflection 4, first plane of reflection 4 is regional with the partial light reflection that light source module 2 sent to the face guard 3 between two adjacent light source module 2.
By using the panel lamp of the chassis 1, the path of part of light is changed by the first reflecting surface 4, so that part of light emitted by the light source module 2 is reflected to a required area to illuminate each part of area of the mask 3, thereby realizing a good illumination effect with uniform brightness and reducing the number of the light source modules 2; and the side wall of the chassis 1 is processed into the first reflecting surface 4, so that the structure is simple, the installation is convenient, and the cost is low.
To achieve the above object, the structure of each component of the panel light will be described in detail below by taking the panel light to which the chassis 1 is applied as an example.
As shown in fig. 4, the light source module 2 includes a strip-shaped substrate 21 fixed on the chassis 1, LED beads 22 fixed on the strip-shaped substrate 21, and a light distribution element 23 covering the outside of the LED beads 22. The number of the LED lamp beads 22 on the strip-shaped substrate 21 is determined according to the requirement of the whole lamp power. The light source module 2 emits warm light located in the middle and extending along the light source module 2 and cool light located on both sides of the warm light, the cool light is usually white light, and the warm light is usually yellow light.
The light distribution element 23 may be a lens, and forms a four-quadrant symmetric or rotational symmetric light distribution form. When the light distribution element 23 is a lens, the lens is an optical transparent PC material, and the light direction is controlled by different thickness changes of the lens. The center of the lens is thin, the edge of the lens is thick, so that large-angle light emission is guaranteed, and a larger irradiation range is achieved.
The mask 3 may be a diffusion plate. The diffusion plate is a milky white plate with a diffusion effect, the diffusion plate is made of transparent PC, PMMA or PP base materials, a certain amount of diffusion particles are added into the base materials, and the primary transmittance is 50-55%.
As shown in fig. 3, the mounting portion 13 may be a long strip, the mounting portion 13 may be provided with a slot, and the light source module 2 is fixed on the mounting portion 13 in a clamping manner. The inner sides of the two pairs of sidewalls 11 are plated with a reflective layer and arranged as the first reflective surface 4. The warm light emitted by the light source modules 2 is emitted to the face mask 3 from the space between the first reflecting surfaces 4, the direction of the cold light is changed through the first reflecting surfaces 4, the cold light is mixed with the warm light emitted by the same light source module 2, and the warm light emitted by two adjacent light source modules 2 is partially overlapped.
In the prior art, the light emitted from the same light source module 2 to the face mask 3 is alternately arranged by cold light, warm light and cold light. When the light source modules 2 are arranged, the cold lights positioned on the same side in two adjacent light source modules 2 need to be overlapped (at this time, the warm lights are overlapped more) so as to achieve good illumination effects of uniform color and uniform brightness. Therefore, the distance between two adjacent light source modules 2 needs to be smaller, so that the number of the light source modules 2 is larger.
In the present application, the angle of the cold light is changed by the first reflecting surface 4, so that the cold light is emitted to the area where the warm light is located, and the cold light and the warm light are mixed, so that the light emitted by the same light source module 2 to each position of the face mask 3 is the light with a more uniform color of the mixed cold light and warm light. When setting up light source module 2, make two adjacent light source module 2 warm less part overlap, can illuminate the central point between two light source module 2 and put to make the luminance of face guard 3 even can. Therefore, the distance between the two light source modules 2 can be set to be larger, the number of the light source modules 2 is reduced, and the cost of the panel lamp is reduced.
The side walls 11 on the inner side are connected by a top surface 12, and the top surface 12 may be an arc surface or a plane parallel to the plane of the mounting portion 13. With the arrangement, when the panel lamp is thinner, the gap height between the top surface 12 and the face mask 3 is effectively ensured, and the possibility that the part of the face mask 3 opposite to the top surface 12 appears bright lines due to insufficient gap height is reduced. The height of the gap can be more than or equal to half of the height of the panel lamp, and the brightness uniformity of the panel lamp is improved as much as possible on the basis that the panel lamp can be thinner. Of course, the side wall 11 located at the inner side may also extend obliquely directly to the intersection or the like.
The inclination angles a (shown in fig. 3) of the positions of the same first reflecting surface 4 are the same, i.e., the first reflecting surface 4 is an inclined plane, and each first reflecting surface 4 is a diffuse reflecting surface to reflect the cold light to a desired position. Furthermore, the reflecting surfaces on both sides of the same light source module 2 are inclined reversely and have the same inclination angle a. Through the arrangement of the mode, the structure is simple, and the chassis 1 is convenient to process.
The inclination angle a of each first reflecting surface 4 may be greater than 155 °. Generally, the light emitting angle of the luminescence light of the light source module 2 is mostly concentrated at about 150 °, and when the inclination angle a of the first reflecting surface 4 is larger than 155 °, most of the luminescence light can be distributed relatively uniformly after being reflected, thereby improving the color uniformity.
In this application panel light, when prior art panel light needs 6 groups light source module 2, this application panel light set up even 2 groups light source module 2 can. A specific application example is described below as an example.
In a 600mm (length) 600mm (width) 40mm (height) panel lamp, 2 groups of light source modules 2 are provided, and the distance between 2 groups of light source modules 2 is 240 mm. The LED lamp beads 22 are single beads of 1W, and the packaging size can be 3.0mm by 3.0mm or 2.8mm by 3.5 mm. Each strip-shaped substrate 21 is provided with 18 LED lamp beads 22, the whole lamp power is about 36W, and the distance between every two adjacent lenses on the strip-shaped substrate 21 is 30 mm. The light incident surface and the light emergent surface of the lens are both in a rotational symmetry structure, the section surface type is a free-form surface, the diameter of the maximum appearance surface is phi 15.5mm, the maximum height is 5.7mm, and light emergent light as shown in fig. 7 is formed. The inclination angle a of each first reflecting surface 4 is 160 °, the top surface 12 is a plane, and the height of the inner side wall 11 is 20 mm.
