Abstract

The utility model relates to a lamp with a reflecting cup, in particular to an LED reflecting cup which comprises at least one cup cavity used for placing an LED light source. The surface of the cup cavity consists of an upper-section non-concave revolution surface and a lower-section non-concave revolution surface. In the utility model, the surface of the cup cavity of the LED reflecting cup adopts two sections of non-concave surfaces which avoid the spotlight phenomenon, while the lower-section non-concave surface is utilized for reflecting light, thus increasing the brightness of the peripheral region radiated by the lamp, so that the lamp is uniform in irradiating brightness, and can guarantee higher brightness.

Description

The LED reflector

Technical field

The utility model relates to a kind of light fixture reflector, particularly a kind of LED reflector.

Background technology

In the existing explosion-proof industry, LED explosion-proof lamp reflector curved surface commonly used adopts concave surface mostly, the light launched of led light source can form the optically focused phenomenon behind the concave reflection of reflector like this, thereby make light fixture can go out to have the situation of the light and shade inequality that center brightness is big, periphery brightness is little of irradiation, and glare phenomenon can appear, and the eyes susceptible that the phenomenon of this dazzle and light and shade inequality can capacity makes the user of service is to tired and be easy to generate and float dry and sense of depression, thereby is unfavorable for physical and mental health, influence operating efficiency.

The utility model content

The purpose of this utility model is to solve existing LED reflector can produce the deficiency of optically focused and glare phenomenon, and the even free from glare of a kind of LED of making light irradiation brightness is provided and makes it to guarantee the LED reflector of high brightness.

The purpose of this utility model is achieved by the following technical solution: a kind of LED reflector, and include at least one glass chamber and be used to place a led light source, the chamber face in described cup chamber is made up of upper and lower two sections non-recessed surfaces of revolution.

The epimere surface of revolution wherein and the angle between its axis are between 40 ° to 50 °.

The hypomere surface of revolution wherein and the angle of axis greater than 0 ° less than 10 °.

The angle of the described hypomere surface of revolution and axis is 7 °

Described reflector is provided with a plurality of glasss of chambeies, this circular array in a plurality of glasss of chambeies

What the chamber face in the cup chamber of LED reflector of the present utility model adopted is two sections non-concave surfaces, non-concave surface has been avoided the optically focused phenomenon, and the non-concave surface that utilizes hypomere comes reflection ray, thereby can increase the brightness of the outer peripheral areas of light fixture irradiation, make light fixture have irradiation brightness evenly and can guarantee that it has higher brightness.

The specific embodiment

Now in conjunction with the accompanying drawings embodiment of the present utility model is further described:

As Figure 1-3, a kind of LED reflector 2 of the utility model embodiment includes at least one glass chamber 21 and is used to place a led light source 4, the chamber face in described cup chamber 21 is by last, following two sections non-recessed surfaces of revolution 211,212 form, and the epimere surface of revolution 211 wherein and the angle between its axis are between 40 ° to 50 °, the angle of the hypomere surface of revolution 212 and axis greater than 0 ° less than 10 °, the described hypomere surface of revolution 212 preferably is made as 7 ° with the angle of axis, cup chamber 21 is by the design of present embodiment, make the upper end surface of revolution 211 effectively guarantee the beam angle of led light source, light in the 100 degree angles that its single LEDs light source self sends is not had block; The light that the hypomere surface of revolution 212 is outside one's consideration single LEDs light source 100 carries out effective orienting reflex, has guaranteed the beam angle and the brightness of single LEDs light source secondary optics.

In the present embodiment, described reflector 2 is provided with a plurality of glasss of chambeies 21, these a plurality of glasss of chambeies 21 circular arrays, by with being used of plurality of LEDs 4 light sources, make the illumination of the lamp body of the refractive body that is equiped with utility model penetrate that more uniform luminance is bigger; And can form the LED explosion-proof lamp of various ways and multiple power, can satisfy the various demands of different occasions illuminations.

Be to be a LED explosion-proof lamp as shown in Figure 4, three screws 5 of led light source aluminium base 3 usefulness are fixed on the housing 1, and guarantee that two planes fully contact; Three screws 6 of reflector 2 usefulness are fixed on the housing 1, guarantee that reflector effectively contacts with the lamp pearl 4 of led light source.

Obviously; though in conjunction with the accompanying drawings the utility model embodiment has been done detailed description; it only is preferred implementation of the present utility model that but those skilled in the art should be understood that above embodiment; and be not qualification to protection domain of the present utility model, any improvement of being done based on invention spirit of the present utility model is all naturally in the utility model protection domain.
