Abstract

The utility model discloses an LED straight lamp structure with large lighting angle, which comprises a radiator, an aluminum substrate on the radiator and an LED light source on the aluminum substrate. A light-permeable shade is connected to two sides of the radiator to form a round tube, and the radian of the radiator in the cross section of the round tube ranges from pi/3 to 5pi/6. The LED straight lamp structure provides large lighting angle and realizes large lighting area while guaranteeing heat dissipation, and is simple in structure and convenient to use.

Description

A kind of big firing angle LED straight lamp structure
Technical field
The utility model relates to a kind of LED straight lamp structure, relates in particular to a kind of big firing angle LED straight lamp structure.
Background technology
LED is because long service life, series of advantages such as environmental protection, be applied to each lighting field very soon, heat radiation and light-emitting zone size are two important indicators of LED lamp, the LED straight lamp has two kinds of forms at present, a kind of be the light-emitting zone maximum have only 210 degree all the other for the radiator part, heat radiation can meet the demands, but available light-emitting zone is little, also having a kind of is all to be luminescent material, does not have radiator, utilizes self-radiating, this structure light-emitting zone can reach more than 300 °, yet though light-emitting zone is big, relatively poor heat radiation has caused power little, therefore, take into account the heat radiation of LED lamp and the difficult problem that light-emitting zone remains LED illumination development.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of big firing angle LED straight lamp structure, this big firing angle LED straight lamp structure can provide big lighting angle under the prerequisite that guarantees heat radiation, realize big light-emitting zone, have simple in structure, the characteristics of being convenient to utilize.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of big firing angle LED straight lamp structure comprises radiator 1, and aluminium base 2 is arranged on the radiator 1, and led light source 4 is arranged on the aluminium base 2, and radiator 1 both sides connect diffuser 3 and form pipe, and in the cross section of formation pipe, the radian value of radiator 1 is π/3～5 π/6.
The radian value of described radiator 1 is π/3.
The radian value of described radiator 1 is 2 π/3.
The radian value of described radiator 1 is a pi/2.
The radian value of described radiator 1 is 5 π/6.
The material of described radiator 1 is an aluminium.
The utility model compared with prior art has the following advantages:
1) can under the prerequisite that guarantees heat radiation, provide big lighting angle, realize big light-emitting zone.
2) simple in structure, be convenient to utilize.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
As shown in drawings, a kind of big firing angle LED straight lamp structure comprises radiator 1, aluminium base 2 is arranged on the radiator 1, led light source 4 is arranged on the aluminium base 2, radiator 1 both sides connect diffuser 3 and form pipe, in the cross section of formation pipe, the radian value of radiator 1 is π/3～5 π/6.The material of described radiator 1 is an aluminium.
Operation principle of the present utility model is:
Led light source 4 produces heat in the time of luminous, heat is delivered to radiator 1 by aluminium base 2, and finally is delivered in the air by radiator 1, and the light that led light source 4 sends penetrates by diffuser 3.Prove in the experiment, when the radian value of radiator 1 during greater than 5 π/6, radiating effect is good, but the light angle of departure of LED lamp only is 210 degree, light-emitting zone is less, when the radian value of radiator 1 during less than π/3, the light angle of departure of LED lamp is 300 degree, can guarantee bigger light-emitting zone, but can cause that heat radiation is bad this moment, have a strong impact on the security performance and the service life of LED lamp, therefore, in the cross section of pipe, when the radian value of radiator 1 is π/3～5 π/6, can guarantee radiating effect on the one hand, can guarantee that on the other hand the LED light fixture has bigger emission angle.In order to guarantee better radiating effect and lower production cost, the material selection aluminium of radiator 1.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong to the protection domain of technical solutions of the utility model according to the utility model technical spirit.
